Application led January 23, 1919. Serial No. 272,732.

To all whom t may concern.'

Be it known that I', JAMES 4MILTON ENG- LISH, a citizen of the United States, resident. of Alliance, Ohio, have invented certain new and useful Improvements in Stoppers for BottomPour Ladies, of which the f ollowing is a specification.

My invention relates to a stopper for bottom pour ladles used -to contain molten metal and is designed to provide a connection for the stopper and a support for the tile protecting the rod from the action of the molten met-al which is utilized to lift the stopper.

In the accompanying drawing:

Figure l shows an elevation of' a ladle partly in section with my invention applied thereto, while Fig. 2 is a detail sectional view showing the specific improvement.l

Fig. 3 is an elevation of a part of the ladle showing the operating means for the stop.

The ladle is shown at A and the stopperwhich is of black lead is shown at B, closing the discharge opening from the ladle. A rod C is detachably connected to the stopper by`a bayonet joint'and after given a quarter .turn the usual space is lled in with a suitable packing, this construction being usual and well known. The sto per rod has projections o on each side a vethe lower end so as to support the protecting tiling b around the rod, this tiling being in sections as shown in Fig. 1 and extending to the top of the ladle above the level of the molten metal within the same. The rod has Va goose neck d which has an adjustable con The adjustment of the stopper rod is effected through a support on the ladle sustaining a vertically movable plate slotted which is actuated by a lever to raise and lower the same.

The lower end of the rod C is reduced Where it receives the stopper B and this lower end has spacedapart flanges or ribs a and these are in the same radial planes with the flanges or ribs a, at the lower end of the full diameter portion of the rod C so that the spaces between the circumferential flanges a overlie the spaces between the lower flan es a and the rod adjacent the anges a and or some distance above the plane of these flanges is recessed, the bottoms of these recesses c being coincident with the side face of the reduced end of the rod. This construction provides f'or a bayonet joint fitting of the stopper B to the lower end of the rod and while providing for supporting the tile on the flanges a provision is made by spacing these flanges apart and by forming the recesses in the rod between and above them for introducing the packing material into the spaces of the stopper, resulting from the bayonet joint connection. 1 j

What I claim is:

A stopper device for bottom pour ladles comprising a rod having its lower portion of reduced diameter to receive the stopper, said reduced portion having flanges spaced 'apart from each other and extending in a direction circumferentially of the rod, flanges spaced apart at the lower end of the full diameter portion of the rod, said flanges being in the same radial planes with the lower flanges and said rod having recesses extending between and above the upper flanges and with their bottoms substan tially coincident with the side face of the reduced diameter portion of' the rod and tiling supported on the upper flanges, all of said langes being integral with the rod, substantially as described. j

In testimony whereof I aflix my signature.
